Description

Technical Field

[0001] The invention belongs to the technical field of road marking equipment, and in particular relates to a movable operating platform of a road marking vehicle. Background Art

[0002] In recent years, my country's economy has developed rapidly, and the construction of highways and roads at all levels has been continuously developed. The market demand for road marking equipment has continued to increase. Among the road marking equipment of highway companies, road marking vehicles have the highest construction efficiency and are the most convenient. Among road marking vehicle equipment, the operating table is an important device for construction personnel to control the marking process, and it is well used on each road marking vehicle.

[0003] At present, the operating tables of the road marking vehicles on the market are mostly fixed directly on the vehicle and cannot be moved. The control panels and operating components are also mostly fixed in position. During the construction process, the construction workers must pay attention to the quality of the marking at any time. Therefore, the fixed operating table is difficult to meet the needs of the construction workers. In addition, different construction workers have different requirements for the position of the control components. Therefore, the fixed position of the control components is also difficult to meet the construction needs. Summary of the invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides a movable operating table for a marking vehicle, which can move freely horizontally in the left and right directions, and also enables the control components to be freely adjusted as needed, thereby greatly facilitating the driver's control of the entire marking process.

[0012] The positioning device includes a mounting plate, a stud, a positioning pin, a spring and a guide sleeve. The lower end of the mounting plate is welded to the channel steel guide rail. A threaded hole that is transparent from front to back is opened on the mounting plate. The stud extends into and is threadedly connected in the threaded hole. A hexagonal head for clamping a wrench is integrally provided at the rear end of the stud. The front side of the hexagonal head is crimped with the rear side of the mounting plate. A three-level stepped hole that is transparent from front to back is opened on the same center line of the stud and the hexagonal head.

[0013] With the above technical solution, mounting holes are provided at both ends of the channel steel rails, and the sliding platform can be installed as a whole at the corresponding position of the marking vehicle through the mounting holes. In addition, a limit partition is fixedly provided in the middle between the front and rear channel steel rails, and the limit partition divides the sliding platform as a whole into two parts from the middle. The left and right ends of the channel steel rails are not closed, so that two sets of operating devices can be placed on this sliding platform at the same time, and can slide to the left and right sides along the two channel steel rails at the same time, and at the same time, it can ensure that the left and right operating devices will not collide and interfere.

[0014] The rollers of the operating device of the present invention are installed on the front and rear sides of the base, supporting the entire operating device, so that the operating device can automatically slide along the two channel steel guide rails driven by the rollers. The positioning plates are welded to the rear side of the base, and the number and position of the positioning plates can be freely determined according to actual needs. The seat mounting bracket, guardrail and grille bracket are all fixed to the base by fasteners. The steering gear assembly and control components are installed on the cross tube on the upper part of the gate-shaped steel pipe frame through an adjustable connecting seat.

[0015] The grille bracket is welded with multiple thin round tubes. On the one hand, it can facilitate the driver to support his feet. At the same time, the large space between the round tubes can also ensure a good field of vision, allowing the driver to more conveniently check the marking situation through this space.

[0016] The circular clamping hole formed by the upper and lower connecting blocks of the adjustable connector clamps the cross tube. Both can rotate freely around the cross tube and move horizontally along the cross tube. When they move to the appropriate position, tighten the bolts to tighten them. In this way, the steering wheel assembly and the control component can be located in the most suitable position for the driver. The transverse friction groove increases the clamping friction to ensure that the adjustable connector does not rotate after positioning. The connector under the control component and the connector under the steering gear are designed according to the actual structure, which is convenient for installation and disassembly.

[0017] When marking different lines on the road, the driver can stand on the left or right operating device to operate. The operating device moves to a suitable position on the channel steel rail, and the positioning device can be used to position the operating device on the channel steel rail. The operating method of the positioning device is: rotate the handle to move the handle along the spiral guide surface at the rear end of the guide sleeve, that is, the distance between the handle and the mounting plate gradually increases, the handle drives the positioning pin to rotate and overcomes the elastic force of the spring, driving the positioning pin to move backward. When the positioning plate moves to the position corresponding to the front and rear of the mounting plate, the handle is rotated in the reverse direction. Under the action of the spring, the positioning pin moves forward and is inserted into the positioning hole on the positioning plate, thereby positioning the entire operating device.

[0018] The stud of the positioning device is threadedly connected to the mounting plate, and the hexagonal head presses against the mounting plate to fasten the stud and the mounting plate together. The front end of the guide sleeve is threadedly connected to the third circular hole to provide support for the rear end of the spring and the rear circumference of the positioning pin to ensure the coaxiality of the positioning pin. The spiral guide surface at the rear end of the guide sleeve plays the role of guiding the handle to move forward and backward, which makes the operation more labor-saving when driving the positioning pin to extend and retract forward and backward. The threaded connection between the guide sleeve and the third circular hole makes it easier to install and disassemble. The spring presses against the guide sleeve, which can also improve the connection strength between the guide sleeve and the third circular hole.

[0019] To sum up, the present invention has scientific principles, reasonable design, compact structure, can be moved left and right, and is easy to adjust and position. It can realize the free horizontal movement of the entire operating platform and also enable the control components to be freely adjusted, thereby greatly facilitating the driver's control of the entire marking process, having good safety and reliability, and greatly improving the quality of marking operations.
